A novel method for the synthesis of 1,1,2-tri-substituted cyclopropanes is reported which involves the reaction of electron-deficient olefins with dibromomalonic ester, dibromocyanoacetic or dibromobenzeneacetic ester promoted by tri-n-butylstibine.The reaction was carried out under mild conditions to give the cyclopropane derivatives in moderate to good yields.Other R3M (M= As,Sb,Bi) reagents as promoter for this reaction have been studied and seem to be less effective than tributylstibine.
